Thepresent. invention relates to. improvements intemplatestand has particular-reference to. a

"template"intendedifor use in connection w a sticker machine,'..althol1'gh"it may he used for otherpurpos'es. a

A sticker machine is used in the wood-working industry for. making mouldings the general idea of. the sticker machine-being to advance a strip ,or stick. ofrwood' to pass over a.rev.olv hle:-cu

"to terwhich latter cuts the desiredjshape into one face of the stick. The. cutter blade is. mou ed :on a. revolvable cutter headwhich-in the standzardflmachinesris.square cross section to pre- 'sent four rectangular facesandan equal number @1112? of corners, the blades being secured to the faces so .as to project beyond the corners.

The positioning of these biladesso asto obtain a desired result is .dfificult because there is no possible way of ascertaining the desired radial distance of the cutting edge iromthe. axis of rotation. a

The only dimension that can be conveniently establishedis the depth to which. the blade pro..- jects beyond the corner or the cuttermhead. 1311.1; 125 since the blade doesrnotproject radial direction, the depth of the projecting blade. does not correspond to the dept/1119f Cut des r dl f9 instance, it is desired zto out into'thestickto the 7' v V v 4 t v V is'first'zcalledito Figure? wh ch shows a, cutter m u ted Qn h Pl-(a l sha fl li ie depth of one half an inch irom a ba e and the blade is made to project from a corresponding line on the cutter head by'the same distance of one half .inch, the blade would cut intothe stick to a depth somewhat less than one half an inch and it is necessary to raise the'lolade somewhat higher than one half inch to produce a one half inch cut. This difference is referred to the trade as the gain and is difficult-to estab: lish and. the correct positioning of-v the blade on the cutter head causes many expensive delays. -40 It is the object of the present invention to provide .a template whichallowsithel gainpr rather the total depth of. projectiono-fwthe blade beyond the corner of the cutterrhead to be establi lished quickly, without any difiiculty and without the display of any particularskill on the part of theoperator.

This machine iskn'own as a "sticker machine and the idepth of cut depends upon 'theldistance which the cutter Lb1aole projects l .beyorldjthe adjacent cornerjjf th'elcutter. head.

,The most convenient vway of adjusting the= .blade to,,thedesirtidQheight, isvby means .offa

gaugeorgtemplate .10 suchras indicated in dotted lines in Figure 9,w hich uses the. adjacent face "ofthe, cutter head as a base. But-since the blade occupies an angular position insteadof a radiaP.

' the ends of the frame position, the desired measurements cannot be applied without being first modified and corrected, as will be easily seen by reference to Figure 10, which diagrammatically illustrates the principle on an enlarged scale.

The cutting action takes place at the vertical centerline indicated at H while the blade is shown at 3. If it is desired to cut into the stick to the depth of one-eighth of an inch as outlined on the vertical center line, the blade must be raised by a distance somewhat more than oneeighth of an inch as defined between the two circles and marked one-eighth of an inch plus gain.

This gain varies with the size of the circle, the gain getting less the larger the circle grows.

It is proposed in the present invention to construct the template I0 in such a manner that, if applied as in Figure 9, it will permit the blade to be adjusted so as to automatically take care of the gain and to compensate for the same.

My template comprises in its pricipal features a rectangular frame [2, a plurality of bars l3 movable in the frame and means associated with for adjusting the bars.

The frame I2 is made in two parts, a rear section l4 and a front section l5, the two sections being similar in shape and being secured to one another to form a support for the operating mechanism. The section I4 comprises an upper member IS, a lower member I! and end members l8 and is strengthened by three vertical braces l9, two of which are formed with elongated vertical slots 20, (see Figure 8).

The section I4 is made of two substantially identical parts which are fastened upon one another by means of screws 2| and which form elongated cavities 22 in the lower frame member l'l adapted to slidably receive rods 24 forming hooks 25 at the ends thereof.

These hooks 25 may be placed against the end of the cutter head, as shown in Figure 9, to insure a proper position of the template on the face of the cutter head. They are adjustable, as is apparent by their construction and may be fixed in adjusted position by means of screws 26 threaded into the sleeves 23 through slots 21 and bearing on the rods 24. When not in use the hook may be retracted and made to disappear in the recess 28 as shown on the right hand side of Figure 8. The rear section l4 has a forwardly projecting flange 29 along the bottom edge thereof. a

The front section I5 is somewhat similar to the rear section and comprises an upper member 30, a bottom member 3| and end members 32. .It also has vertical braces 33 which register with the two outer braces IQ of the rear section l4 and may be secured thereto by means of sockets 34 projecting from the rear faces of the braces 33 into the slots 20 of the braces l9 and clamped to the latter braces by screws 35 threaded into the sockets. The slots allow the front section to be adjusted relative to the rear section.

When the front section is secured to the rear section, the front face of the front section is on a plane with the front face of the flange 29 projecting from the rear section, as clearly appears from Figure 7, and the end members 32 of the front section are flush with the end members l8 of the rear section on the outside, as shown in Figure 4, but are much narrower so as to form pockets 36 therewith, which are bridged by thin end plates 37 secured to the top and bottom members 39 and 3| of the front section by means of screws 38. The top and bottom members 39 and I adjacent relation against the 3| are slightly depressed to receive the end plates so that the faces of the latter are flush with the front face of the front section of the frame.

Upon the frame are mounted, with freedom of vertical sliding motion, a plurality of bars [3 which extend horizontally across the frame, their front faces flush with the front faces of the front section and the flange 29, and their ends being slightly recessed, as at 4|, to fit underneath the end plates 31. The bars are grooved, as at 42, over the braces 33, which themselves are slightly set back to serve as vertical guides for the bars-without pressing the same out of the front plane. The grooves are sufficiently wide to allow of a small amount of play of the bars on the braces. The bars are all of the same width and for the purposes of my invention I find that a width of one-eighth of an inch gives satisfactory results. Each bar terminates, at the ends, in a tooth 43.

The height of the frame is such, relative to the width and number of the bars, that when the bars are arranged in adjacent relation, as. in Figure 1, a considerable space is left above the bars so that the same may be spread or separated as in Figure 2. For spreading the bars I provide, opposite the toothed ends in each side pocket, a toothed spreader or spacer 44, which has a number of teeth 45 adapted for engagement with the teeth of the bars, but spaced in such a manner that when all the teeth are engaged the bars are spaced from one another as shown in Figure 2. It should be observed that springs 46 (see Figures 6 and 2) are interposed between the bars and tend to separate them.

The spreader is movable sidewise in the pocket at each end of the template for engagement with and disengagement from the teeth at the ends of the bars. The position of engagement is shown at the left end of Figure 3 and the position of disengagement at the right end. The spreader is operated by the actuating plate 41 (see Figure 5) which overlies the spreader plate and is shown in dotted line positions in Figure 3. This plate is also accommodated in the pocket at each end with freedom of vertical sliding movement and. is guided vertically by the end member 32 of the front frame section which projects into a groove 48 formed between a rib 49 and the projecting finger piece 50.

The actuating plate has two prongs 5| and 52 projecting from its bottom face and these prongs enter into registering slots 53 and 54 of the spreader plate 44. Both of these slots are curved but it will be noted that the curve in slot 53 begins at a lower point than that in slot 54 so that, when the actuating plate is pushed upward the spreader plate moves into engagement with the bars progressively, beginning at the bottom and proceeding upwardly from tooth to tooth, as the bars spread under the influence of their respective springs 46.

The actuating plate 41 has a tongue 55 projecting from its upper edge so as to overlie the uppermost bar and to compress the bars into resistance of the springs 46 when the actuating plate is moved downward.

The plate 41 has two spaced depressions 56 adapted for engagement by a projection 51 in the cover plate 31 for yieldingly holding the actuating plate in either of its end positions.

The bars are suitably graduated into inches and one-eighth inches to conform to a standard ruler.

' plate shown in-Figure 1.

My template is used as'foll owsf Assuming'itis desired to cut a; mouldingof the cross-section shown in heavy outline on the tem- The first step is to adjust the frontan'd rear sections of'thetemplate relative to one another'so as to establish a suitable base line in' thebottom line of the bottom member 3|"offthe front" sectionfwhich should be adjustedTsoTthatfa"blade'setf'to the height of the base line;when the template'is'u'sed as 'in Figure 9 should "just contact," with a'slight shaving faction, the "bottom of the stick passing through the machine. The "adjustment need never be changed as'lo'ng as the template is used for the same machine or type of machine.

Next a small piece 'ofm'oldin'g jof the desired type is" taken, its end placed" against the front faceof the template anditsoutline'traced, by pencil or other tool, over'theba'seline, assho wn inFigurel. s

, It will be understood thata plurality'of'blades are conventionallyused to cut into a'stick' or moulding at different plac'es'to'p'roduce the continuous curve or other shape" desired. Assuming that four blades are usedas shown in Figure 9,

it is necessary, ofcourse, toarrange the four blades in staggered relation longitudinally on the each end of the'template'by pushing the same upward. The firsteffect of this'movement is that the bars are released from the 'hold of 'the'fingers 55 and' allowed to spread under the influence of the springs 46. But the upward movement of each actuating member also pushes the spreader plate 44 toward the bars, first at the'bottom and then at the top so that theteeth of the spreader progressively engagewith the teeth of the bars,

as the latter spread under the influence of their springs and when the engagement is completed the bars are firmly held by the spreader members in the spaced relation shown in Figure 2.

The teeth on the spreader plate are spaced so that the spacing" between the bars in final position exactly corresponds to the gain to be added for the width of each bar to produce the correct height for each blade'when the template is, applied as in Figure 9. v

To' produce the correct adjustment ofeach blade it is now only necessary toplace the'template behind eachblade as shown in Figure 9 and to raise each blade to the distorted outline of the moulding behind the blade.

Referring now to Figures 8 and 9, it will be noted that in the event the shaft 2 should be slightly out of parallel with the top of the table 1, the rear section M of the frame 12 may be twisted relative to the front section [5. The slots 20 will permit this angular adjustment, and the bottom of the lower member I! may be presented parallel to the shaft 2, while the bars l3 will be parallel with the table top.

In making the lower surface cut as indicated by the numeral 32 in Figure 1, the template may be turned upside down from the dotted line position. v 2. A template of the character described comtion'shownin Figures. The'blade for this particular cut "is' then adjusted until it strikes the edge l6 of the upper member l6 (see Fig, 7).

-It "will be noted in this connection that the dis- "tance fromthe edge 16' to the top 30' of the member 30 1s always the sameas the distance from the bottom 29 of' the flange 29 to the lower edge3l" of the bottom member 3| (see Fig. 7).
